I think that, as with many things, we just need to find a middle ground. There is little that is ideal about living through a global pandemic (for any of us).
I do think that mask wearing by the majority protects us all, so I support this being the law to wear a mask unless medically exempt.
I think it's fine for shop staff to politely ask if someone has a mask. If someone replies that they are medically exempt, they shouldn't be challenged further on this by shop staff. I totally agree that people shouldn't be expected to disclose confidential medical information in the middle of a shop.
If people are unhappy being asked, the people unable to wear a mask could consider some of the following options:
- they could wear a visor (for many people this would resolve the problem that mask wearing poses as it doesn't restrict airflow although I get that it's not suitable for everyone, eg in the case of learning disabilities it may not resolve the problem. However for your friend with epilepsy that would probably resolve the issue completely)
- wear a badge/lanyard
- do online shopping/click and collect/get someone to do their shopping for them
I think that the anti-mask brigade aren't doing those who are genuinely medically exempt any favours by making such a fuss about it all. It should be the case that the vast majority of people are wearing them, then by definition those people not wearing them are medically exempt, but there's so many people just generally resisting it that I think a polite question/reminder from shop staff is helpful.
I think we all need to appreciate that masks are for the greater good (including the medically exempt) , and here to stay for the forseeable future. We need to get behind them for those of us that can wear them, and be kind to those that can't (by that I mean it's ok to remind people to wear a mask, but accept their answer if they are medically exempt and not push them on it). It's not ideal, it's not how we would choose things to be, but it's how it is.
